Medical high-resolution image sharing and electronic whiteboard system: A pure-web-based system for accessing and discussing lossless original images in telemedicine

“…From the perspective of transmission efficiency, the progressive transmission characteristic of JPEG2000 from [13,15,16] was slightly better than our method, but it increased computing pressures on server coding, client decoding and reconstruction. From the perspective of diversified clients, the methods of [13,15,16,25] were C/S architecture, the software products of client needing to be independently developed to adapt to different operating systems and hardware characteristics. The method of [25] even required additional installation of JAI SDK and a virtual machine.…”

“…In addition, we have done a comparative analysis with similar studies [13,[15][16][17]25,27]. It is very important to transmit data at bandwidth as low as possible while maintaining the original image quality on the Internet.…”

“…It is very important to transmit data at bandwidth as low as possible while maintaining the original image quality on the Internet. Therefore, the methods of [13,15,16] adopted JPEG2000 framework, the methods of [17] and our method adopted tile-based transmission and Local Cache to reduce the amount of data transmission, the methods of [25,27] adopted the entire transmission. From the perspective of transmission efficiency, the progressive transmission characteristic of JPEG2000 from [13,15,16] was slightly better than our method, but it increased computing pressures on server coding, client decoding and reconstruction.…”

“…(3) Using new network interactive technologies to change the whole transmission into on-demand transmission [13][14][15][16][17][18]. For example, [13][14][15][16] used JPEG2000, which has been included in DICOM supplement [22] and has very good network transmission characteristics, including Region of Interest (ROI), progressivity and scalability. But JPEG2000 has not been directly supported by web browsers and desktop image browsers in the mainstream market.…”
